MICROANATOMY

Detailed explanation-1: -The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium.

Detailed explanation-2: -Each bundle of muscle fiber is called a fasciculus and is surrounded by a layer of connective tissue called the perimysium. Within the fasciculus, each individual muscle cell, called a muscle fiber, is surrounded by connective tissue called the endomysium.

Detailed explanation-3: -The interstitial connective tissue of muscle is subdivided into the epimysium (surrounds the entire muscle), perimysium (surrounds large angular fascicles divided into primary fascicles of 10–100 fibers), and endomysium (surrounds individual muscle fibers).

Detailed explanation-4: -Epimysium: The outermost layer of tissue surrounding the entire muscle. Perimysium: The middle layer surrounding bundles of muscle fibers. Endomysium: The innermost layer surrounding individual muscle fibers.
